In one aspect, there is a method to define a geographical zone, whichcan be in two or three dimensions, and which can be utilized to regulatea movable entity that has a transponder or subscriber device. The devicecan be a cell phone, PDA, pager, computer or similar device, which isconfigured to be in wireless communication with other devices through asuitable network.

The method comprises loading from a computing device to a memory in atransponder or subscriber device a plurality of coordinates. Thecoordinates are mapped on a pixilated image so as to assign one pixel toeach coordinate of the plurality of coordinates. The distance betweeneach assigned pixel is configurable. The plurality of assigned pixelsare connected with lines forming a contiguous line, and the connectedline encloses an area in the pixilated image. The pixels that lie on thelines in order to form a contiguous array of pixels that enclose a shapein the pixilated image are activated. In another aspect, the method todefine a geographical zone allows for regulation of the movable entityby monitoring, controlling and visualizing the status of the entity. Thestatus of the entity may be movement, non-movement, and position of theentity. The movable entity is controlled and monitored depending on thelocation of the movable entity relative to said geographical zone.

In another aspect, the plurality of coordinates are entered by a user ofa computer device and transmitted to the transponder or subscriberdevice. The user is allowed to enter geographical coordinates in athree-dimensional sense by allowing a user to select points in a map ina computer by clicking on the map and calculating the geographicalcoordinates of each selected point in the map. In another aspect, theuser is allowed to enter geographical coordinates by typing on thecomputer the longitude and latitude. The plurality of geographicalcoordinates can defined either by various systems including, but notlimited to, the Mercator system and/or a latitude and longitude system.

In yet another aspect, the position of the movable entity in relation tothe geographical zone as described in the method to define athree-dimensional geographical zone is determined by the steps oflocating the transponder or subscriber device within the pixilated imageby activating a pixel corresponding to the geographical coordinateswhere the transponder or subscriber device is located. Two verticallines are extended in opposite directions and originating from thepixel, two horizontal lines are extended in opposite directions andoriginating from the pixel. The number of times each line crosses theboundary of the geographical zone is determined, and an outside statusis assigned to each line that crosses the boundary a even number oftimes. An inside status is assigned to each line that crosses theboundary a odd number of times. The transponder or subscriber device isidentified as being inside the boundary if the status of three out offour lines indicate an inside status.

In another aspect, a subscriber device has a ground- orelevation-positioning system receiver that calculates the transponder orsubscriber device coordinates, and allows a user or control center toidentify the location of the movable entity in the pixilated image asone pixel in the computer image.

In another aspect, the geographical area is a geometrical shape such asa square, rectangle, triangle, circle, oval, or trapezoid in two orthree dimensions. The shape of the geographical area can also be theshape of a non-geometrical shape such as the shape of the borderdelimiting a building, address, street, state, city, county, or country.

In one aspect, there is a method to define a geographical zone in two orthree dimensions utilized to regulate a movable entity having atransponder or subscriber device. The method comprises allowing a userto enter a plurality of waypoints, each waypoint in the plurality ofwaypoints being defined by a geographical coordinate and a radius;wherein the geographical coordinate in two or three dimensions isrepresented by a latitude and longitude and elevation, and the radius isrepresented by a distance magnitude; and loading the plurality ofwaypoints on a transponder or subscriber device.

In another aspect, the transponder or subscriber device can determinewhether the transponder or subscriber device is inside or outside thegeographical zone in two or three dimensions by obtaining globalpositioning coordinates, and calculating whether the global positioningcoordinates are inside at least one waypoint of the plurality ofwaypoints. The shape of the geographical area is the shape of anon-geometrical shape. The elevation relationship and positions can bedetermined by nodes set at different elevation levels.

In another aspect, all waypoints in the plurality of waypoints have thesame coordinate but different radii, such that all the waypoints in theplurality of waypoints are concentric.

In one aspect, there is a method to identify a geographical area in one,two, or three dimensions for regulating a movable entity. The methodcomprises allowing a user to identify a geometrical area, region orspace in a computer map. The geometrical area, region or space uses twoor more coordinate attributes, and the identified geometrical area,region or space is divided into a grid. A user is allowed to select atleast one section from within the grid in order to define a geographicalarea, region or space. The at least one section is associated with atleast one pixel in a pixilated computer image such that the pixelsselected by the user in the identified geometrical area are identifiedas being in the geographical area, region or space. The pixilatedcomputer image is loaded to a memory in a transponder or subscriberdevice.

In another aspect, the pixilated computer image has a directlyproportional number of columns and rows as the identified geometricalarea, region or space. Alternatively, the pixilated computer image hasthe same number of columns and rows as the identified geometrical area,region or space. In another aspect, the geometrical area, region orspace is rectangular or circular. In yet another aspect, a secondgeographical area, region or space is defined by a plurality ofgeographical areas, regions or spaces.

In one or more embodiments, the identified geometrical area, region orspace is divided into a grid of three-dimensional squares and/orrectangles. The three-dimensional squares and/or rectangles of the gridmay have various depths. The user is allowed to select at least onesection from within the three-dimensional grid in order to define athree-dimensional geographical area, region, or space. The at least onesection is associated with at least one pixel in a pixilated computerimage such that the pixels selected by the user in the identifiedgeometrical area are identified as being in the three-dimensionalgeographical area, region or space. The pixilated computer image isloaded to a memory in a transponder or subscriber device.

In yet another aspect the movable entity has a transponder or subscriberdevice associated with the entity and located in the geographical area,region or space. A position of the transponder or subscriber device isobtained from a ground or elevation positioning unit operably connectedto the transponder or subscriber device. The position of the transponderor subscriber device is correlated in the geographical area, region orspace to a representative position of the transponder or subscriberdevice in the pixilated computer image. The representative position ofthe transponder or subscriber device is determined as to whether thepixilated computer image falls on a pixel that is flagged as being inthe geographical area, region or space.

The present disclosure provides a solution for providing wirelesscommunication devices with relatively precise location awareness, systemmonitoring and area-specific messaging capabilities in environmentswhere an accurate GPS position may not be able to be acquired, such aswithin a multi-story building.

The system-monitoring component performs health checks and validitytests on location nodes within an enabled environment, while thearea-messaging component provides area-specific messaging to enabledwireless communication devices.

As used in this disclosure, “location node” is a stationary programmabledevice with a wireless transceiver, which is “Bluetooth™” capable forexample, and a micro-controller. The location node is preferablyprogrammed with one or more of its own device or “friendly”name-selection parameters, geographical positions, max power settings,installation identifiers, floor numbers and payload types.

A wireless communication device operable to detect a plurality oflocation nodes is disclosed. A wireless communication deviceperiodically interrogates its environment and determines which locationnode is most practically near. The wireless communication device thencommunicates to that location node, and requests that any additionaldata information relevant to the specific location associated with thatlocation node be sent back to the wireless communication device.

The most practically near node is defined as the node that is located atthe closest accessible location to the movable entity. For example, awireless communication device located on the second floor of amulti-story building may be closest to a location node located on theceiling of the first floor, and may be next closest to a location nodelocated on the second floor. Although the location node on the firstfloor is actually closer in distance to the movable entity than thelocation node on the second floor, since the location node on the firstfloor is not easily accessible to the movable entity located on thesecond floor, the location node on the second floor will be consideredthe most practically near node to the movable entity.

In one or more embodiments, the present disclosure relates to a systemand method for the monitoring of and messaging to wireless communicationdevices within a predefined space, wherein the wireless communicationdevice can be any wireless communication device with receiving andtransmitting capabilities such as a cell phone, PDA, lap top computer,desktop computer and pager. The system and method utilizes, in itssimplest form, at least two elements: at least one wirelesscommunication device and at least one location node. When the system isactivated, the wireless communication device will determine all of thelocation nodes within range. The wireless communication device will thendetermine the location of the most practically near location node. Thewireless communication device can then request information specific toits location from this most practically near location node.

It should be appreciated that for simplicity and clarity ofillustration, elements shown in the Figures and discussed below have notnecessarily been drawn to scale. For example, the dimensions of some ofthe elements are exaggerated relative to each other for clarity.

Management and monitoring devices of assets and individuals that useground positioning systems allow users to track the position ofindividuals, vehicles, cargo and other movable entities. The method andsystem described below utilizes a transponder or subscriber device thatcommunicates over cellular and satellite communication networks incombination with GPS satellites capable of providing position and statusinformation of the movable entity on a global scale. Additionally thereis the ability for more precise monitoring of assets and individuals.The transponder or subscriber device allows interaction with and controlof a wide range of peripheral devices, including, but not limited to,operating the movable entity according to pre-configured geographicalzones and triggered events.

A transponder or subscriber device can be mounted, attached,manufactured or otherwise included upon or in various articles orentities. Such individuals, articles or entities may include vehicles,aircraft, cargo, persons, animals or any other item where tracking itsmovement and/or location is beneficial. Within the context of thedisclosed tracking system, the transponder or subscriber device works tocollect, process and communicate information about the movable articleor entity to which the transponder or subscriber device is associated.Furthermore, when requested, the transponder or subscriber device canissue various commands and instructions to the local article, entity,and/or command center.

The transponder or subscriber device has the features, flexibility, andcapability of an intelligent device. The transponder or subscriberdevice may contain a Central Processing Unit (CPU). The CPU has at leasta 4-bit processor, which can interface with at least one modem(cellular, satellite, and others), at least one GPS receiver, at leastone memory module, and/or other peripheral devices. Other components ofthe transponder or subscriber device may include, but are not limitedto, at least one GPS antenna, at least one modem antenna, at least oneserial port for communication and configuration, and at least onemultiple connector pin which contains at least one input and at leastone output. The at least one input and output are configurable to beassociated with a configurable event or configurable operation.

In one or more embodiments, any or all of thecomponents are co-located on the same integrated circuit (IC) chipwithin the transponder or subscriber device. The components of thetransponder or subscriber device depend upon which capabilities themovable entity requires.

Among its many capabilities, the CPU of the transponder or subscriberdevice can be configured to manage configurable events or configurableoperations. Managing events means that among other capabilities, thetransponder or subscriber device can report, observe, recognize,process, and analyze numerous configurable events or configurableoperations. In addition, the transponder or subscriber device can giveand respond to various commands, effectuate numerous events in its localinstallation, and contain a history recording component.

An event message can be triggered by physical and logical eventsincluding the event message itself and/or other such information. Othersuch information includes, but is not limited to, latitude, longitude,elevation, speed, direction, time, state of all the inputs, state of alloutputs, event reason or source, and/or any other relevant informationconcerning the entity.

The transponder or subscriber device is configurable to include as fewor as many configurable logical events or physical events as the userdesires. Events may be physical or logical. Logical events may be basedon rules using a combination of the GPS position of the movable entity,and one other factor, such as time or speed. However, logical events canbe based upon a combination of factors. Physical events are those eventsthat are physically manifested by the individual, the vehicle, or theobject being tracked.

Other configurable events or configurable operations include thelocation of the vehicle, individual or object in terms of latitude,longitude, and/or elevation; the time and corresponding location of thelast configurable event reported; the direction of the vehicle,individual or object; the state of any assigned inputs or outputs orchange thereof; a pre-selected distance; a pre-selected time interval;pre-selected intervals based upon date and time reference; apre-selected schedule for reporting and recording any of theconfigurable events or configurable operations; a pre-selected speed;length of relative stationary time; and length of non movement for anindividual or object.

Additional configurable events or configurable operations include theentering or exiting of a pre-set waypoint or a pre-set zone in amulti-dimensional space such as two or three dimensions being thelongitude, latitude and elevation coordinates, namely the x, y and zcoordinates. A waypoint is a circular, cylindrical, or spherical areadefined by a geographical center point and radius in themulti-dimensional space. The area or space defined by the waypoint isconfigurable by changing the radius and the position of the geographicalcenter point. A zone is an irregular region defined by a series of linesegments enclosing an area or space.

The configurable events or configurable operations or combinationsthereof can be processed in order to transmit a specific message,respond to a specific query or command, enable or disable a specificmechanism, or recognize a specific event. For example, the CPU can beconfigured to process that, if at a pre-selected time the individual,vehicle or object has not moved a pre-selected distance, then thetransponder or subscriber device is sent a command to alter the state orconditions of the individual, vehicle, object, transponder or subscriberdevice.

The configurable events or configurable operations may occur in manysituations. These situations include, but are not limited to, whereconfigurable events or configurable operations occur in response to acommand; where configurable events or configurable operations occur inresponse to a query, or where configurable events or configurableoperations occur upon recognition of pre-selected conditions.

Configurable boundaries or geographical zones may also be employed andcan be configurable to any shape the user desires. For example, theboundary or zone can trace the border of a building, floor of a buildingor structure, part of a building, part or whole of a facility, a campus,a select portion of a building falling within a GPS address designation,a state line, or trace the route of a selected highway or path. Theboundary or zone can trace the border of the premises of a school zone,a no-fly zone, a city, etc. The boundary or zone can also be a geometricshape or non-geometric shape in a multi-directional coordinate sense. Afurther benefit of the present disclosure is that the transponder orsubscriber device can be updated and configured locally or wirelessly.

In one embodiment, the power source of the transponder or subscriberdevice, is a fused main power-in source with a recommended operating ina range between 12 and 24 volts. One embodiment contemplates low powerconsumption (65 mA or less) during normal operation. Furthermore, thetransponder or subscriber device 105 includes circuitry for charging anoptional backup battery. If the primary power source supply is below aminimum acceptable level, the transponder or subscriber device 105 willautomatically switch to a backup power source as well as transmit amessage identifying that the primary power source is at a critically lowlevel.

The transponder or subscriber device 105, such as a cell phone or PDA,is a small and affordable unit with numerous features. The external viewof the transponder or subscriber device is illustrated in FIG. 3. In oneembodiment, the housing 335 of the transponder or subscriber device 105is manufactured from plastic, metal, or any other material thatfunctions to protect the inner components from external events such asphysical damage, dust, water, excessive temperatures or any other eventwhich could affect the integrity of the transponder or subscriberdevice. In one or more embodiments, the transponder or subscriber device105 contains external communication ports, a multiple pin connector, atleast four control outputs, a modem antenna connector, severalindicators and/or a GPS antenna. In another embodiment, a Bluetooth™antenna is incorporated in the transponder or subscriber device 105.

There can be a passenger counter, which can interface with several doorinfrared motion sensors for the purpose of counting the number of peopleentering or exiting from at least one door of, for instance, a buildingor a room. A serial port can also be used to test and configureapplications within the transponder or subscriber device 105. In oneembodiment, the serial port functions as a programming port which isused when programming the unit for the first time or re-programming theunit's core program.

The indicators associated with the transponder or subscriber device 105can be for any type of connection, signal, power level, status, and anyother similar communications. In one embodiment, an indicator is alight-emitting diode (LED) that appears red when the transponder orsubscriber device 105 has power connected to it. Another indicator canbe an LED that blinks green at a rapid pace when the GPS receiver isestablishing a connection and slowly blinks green when a connection isestablished. Another indicator can be an LED light that blinks green forevery message received, and red for every message sent. Anotherindicator can be an LED that is red when the cellular modem 220 isroaming, and is green when it is at home.

Transponder or Subscriber Device Firmware Configuration

The transponder or subscriber device 105 has numerous features,functions, and capabilities described below. The transponder orsubscriber device 105 is an intelligent device controlled by an at least4-bit processor 210. FIG. 2 depicts one embodiment where the processor210 has the capability to interface with a GPS receiver 215, a cellularmodem 220, a Bluetooth™ transmitter/receiver 225, a memory module 280,and a satellite modem 230.

The transponder or subscriber device 105 can be configured to report,observe, and analyze numerous logical events. The transponder orsubscriber device is also configurable to give and respond to variouscommands, and contains a configurable history-recording component. Afurther benefit of the present disclosure is that all the configurationsto the transponder or subscriber device 105 can be done locally orwirelessly. Thus, the user is able to configure any features includingthe entire operating system of the transponder or subscriber devicewirelessly. This wireless configuration can be accomplished through theuse of the cellular modem 220, the Bluetooth™ transmitter/receiver 225,or any other wireless means.

Moreover, the transponder or subscriber device 105 can be configuredlocally through connecting to a serial port. Another benefit of thepresent disclosure is that during wireless or local configuration, thetransponder or subscriber device 105 continues to operate normally. Thismeans that the transponder or subscriber device 105 can be configuredwith losing little to no operability. Wireless configuration commandschange the parameters used for processing physical and logical events onthe fly. Wireless operating system updates are achieved using twoexecutable code spaces, and a temporary code space for loading new code.Once the uploading of new code into the temporary code space iscompleted, the transponder or subscriber device reboots, copies the newcode into the secondary executable code space, and resumes executionwith the most recent update.

FIG. 4 is an exemplary screen shot of the user interface for configuringthe physical and logical events within the transponder or subscriberdevice in one embodiment. FIG. 4 serves only as an example of a generalinterface, with which the user can interact to configure the transponderor subscriber device 105. One feature of the present disclosure is thatconfiguring the transponder or subscriber device does not require theuser to know scripts or hard-coded parameters. Instead, the presentdisclosure includes a software application with which the user caneasily interface via logical windows, tabs, fields, checkboxes and radiobuttons to configure the transponder or subscriber device.

FIG. 4 is a screen shot of a window that interfaces with the user toconfigure the transponder or subscriber device 105. The window 400 hasat least four tabs 401 from which the user can choose. The first tab 402directs the user to a window 400 for configuring the cellular modem 220of the transponder or subscriber device 105.

Events can be physical or logical. Physical and logical events triggerthe sending of a message over the air when certain conditions are met.Most logical events are based on rules using a combination of the GPSposition and one other factor, such as time or speed. The event messagetriggered by physical and logical events includes, but is not limitedto, the event message itself, and such information including latitude,longitude, speed, direction, time, state of all the inputs, event reasonor source, and any other relevant information. The logical events areusually software driven, calculation based, and typically draw from GPSpositions and/or positions from location nodes. The transponder orsubscriber device 105 is configurable to include as few or as manylogical events as the user desires. One embodiment includes at least sixdifferent configurable logical events.

The first logical event of one embodiment is a feature that reports thelast known location of the transponder or subscriber device for aspecified interval of time. The status report to the user may consist ofother parameters such as latitude, longitude, speed, direction, time andthe state of the inputs. An example of a first logical event is wherethe user configured the time reporting interval for 60 seconds. Thismeans that in this scenario, the last known location status andapplicable parameters are reported every 60 seconds. This time-reportingfeature gives the user flexibility, and the option to lower the cost ofdata transmission.

The second logical event of an embodiment is a feature that furtherrefines the reporting capabilities of the time reporting feature. Thisevent is Smart Time Reporting. The Smart Time Reporting featurefunctions to transmit a report only when the vehicle has moved apre-selected distance since the last transmitted report. Thus, a usercould configure the transponder or subscriber device 105 to report itslocation and applicable parameters by selecting a timed reportinginterval in terms of seconds and a distance in terms of meters. Forexample, a user could select the time reporting interval for 60 secondsand the distance for 1000 meters. This would mean that every 60 secondsthe transponder or subscriber device would send a report unless thetransponder or subscriber device 105 has not moved at least 1000 meterssince the last report. This Smart Time Reporting feature allows the userto tailor the amount of reporting and, thus, tailor the cost of datatransmission.

Another contemplated reporting feature is a scheduled reporting feature.This feature sets the transponder or subscriber device's reportingfeature on an interval based upon a date and time reference. Thus, theuser can configure the transponder or subscriber device to reportlocation and the other parameters on pre-selected days and hours of theweek, month, or year. For example, a user could use the scheduledreporting feature to configure the transponder or subscriber device toonly report at 8 am, 12 pm and 4 pm on weekdays and only once perweekend day. Another feature not depicted is a satellite scheduledreporting feature where the same scheduled reporting capabilities areapplicable, only the message is transmitted via an optional satellitemodem 230.

A third logical event of an embodiment is a speeding feature. Thetransponder or subscriber device 105 can be configured to send reportsdependent on the speed or movement of the individual, vehicle or articlethe transponder or subscriber device 105 is associated. Thus, events aregenerated and recorded when a speed threshold has been exceeded, andwhen the speed has crossed below the threshold. When the transponder orsubscriber device 105 crosses back below the threshold, an event messageindicating this occurrence as well as a third message is transmittedindicating the maximum speed reached during the period when thetransponder or subscriber device 105 was above the speed threshold. Thespeed time filter gives the user the option to set a time period interms of seconds to allow the individual, vehicle, or article to crossthe speed threshold without sending a message. This filter also allowsfor efficient data transmission. For example, the user can set the speedtime filter for 15 seconds, which allows the vehicle to speed for 15seconds without sending a report. Similar to the other logical events,the event message can also include information such as the latitude,longitude, elevation, speed, direction, time, and state of the inputs.

The transponder or subscriber device 105 can be configured to sendreports dependent on the amount of time the individual, vehicle orarticle has been essentially relatively stationary. The event messagerecords the time and location corresponding to when the threshold wasexceeded.

Geofencing

The next logical event of one embodiment is a “geofencing” feature,which is the creation of a configurable boundaries or geographical zonesfeature. This feature consists of generating events when the transponderor subscriber device travels through waypoints and zones. A configurableboundary or geographical zone may be constructed through a combinationof waypoints and/or zones. Because of this combination, the configurableboundary or geographical zone can be constructed in a very specificshape, which allows for the outlining of specific borders or routes. Awaypoint is a circular area, cylindrical area, or spherical area definedby a geographical center point and radius. The area defined by thewaypoint is configurable by changing the radius and the position of thegeographical center point. Thus, the boundary created by the waypointsand zones is configurable.

In one embodiment, the transponder or subscriber device 105 is loadedwith a plurality of waypoints, each waypoint is defined by a coordinateand a radius. A zone can be defined by a plurality of waypoints. Thus,for example, a building, campus, part of a building, and/or a city canbe defined by two waypoints in multiple dimensions.

Using GPS data, the transponder or subscriber device, for example, cancalculate whether it is located within two waypoints that define a cityin two dimensions or three dimensions, namely longitude, latitude, andelevation. If the transponder or subscriber device determines that it islocated inside one of the two waypoints, then the transponder orsubscriber device 105 assumes that it is within the limits of the city.

The third dimension, namely the elevation, is defined by nodes locatedat different levels of elevation with which the transponder orsubscriber device communicates. Also, more precise longitude, latitude,and elevation coordinates can be defined by the nodes, in a mannernormally beyond GPS precision and ability.

A zone is an irregular region defined by a series of line segmentsenclosing an area. In one embodiment, each zone contains 3 to 256 ormore deflection points for creating the line segments defining thisirregular area. In one embodiment, this irregular area can create aconfigurable boundary or a geographical zone. The properties of a zoneinclude a name, description, and a flag determining if the zone is anoff-limits zone or an enclosed zone.

In one embodiment, a geographical zone may be created by selecting aplurality of coordinates and downloading the coordinates to thetransponder or subscriber device 105. The plurality of coordinates maybe in the Mercator system. Next, the transponder or subscriber device105 assigns each coordinate to a pixel in a pixilated image that isloaded in the transponder or subscriber device 105. In order to performthe assignment, the transponder or subscriber device 105 utilizes logicto define a “bounding” square or box around the plurality ofcoordinates. Then the bounding box is pixilated, and the pixels whereall the coordinates fall are marked as activated. Once the pixels foreach coordinate are assigned, lines are extended from one pixel to thenext so as to form an enclosed area in the pixilated image. The pixelsthat lie in the path of the lines between the activated pixels are alsoactivated. Thus, an enclosed and contiguous line of pixels is formed.

Waypoints and zones are built by the operations data processor 173. Oncea waypoint and/or zone has been built, it can be used with thetransponder or subscriber device loads. Transponder or subscriber deviceloads are a collection of zones and waypoints slated to be loaded on atransponder or subscriber device 105. These loads are loaded onto thetransponder or subscriber devices with the configuration utility 172.

FIG. 5A illustrates a pixel map 500 of a zone in a broad two-dimensionalsense. After all the deflection points for a given zone are uploaded,the zone is saved in the memory module 280 of the transponder orsubscriber device 105 in the form of a pixel map 500. The pixel map 500is created by first drawing a square around the entire area of the zone.In one or more embodiments, the square is then divided into an80/80-pixel map. Each pixel 505 is a square. These squares are then usedto draw the outline shape 510 of the zone 515. A geographical area isthen mapped to each pixel 505 of the pixel map 500. A position fix 520in the pixel map 500 is mapped from the current geographical location ofthe individual, vehicle, or article. In another embodiment, the pixelmap 500 of a zone can be depicted in a broad three-dimensional sense.

A test is performed for each zone for each position fix 520 in order todetermine if the transponder or subscriber device 105 is located insidethe zone 515 or outside the zone 515. Thus, for each zone 515, the teststarts with a simple check to determine if the position fix 520 islocated inside or outside the pixel map 500. If the current position fix520 is located inside the pixel map 500, a more extensive test iscompleted by plotting the position fix 520 inside the bounding box, anddrawing at least four lines in at least four directions (for example,north, south, east and west) 525 from the position fix 520 to theborders of the pixel map 500. Subsequently, the number of zone boundarycrossings 530 is counted for each of the at least four lines 525.

Multiple boundary crossing tests are performed for accuracy. In one ormore embodiments, if a given line 525 crosses an odd number of zoneboundaries 510, the position fix 520 is considered to be located insidethe zone 515. In one or more embodiments, if a given line 525 crosses aneven number of zone boundaries, the position fix 520 is considered to belocated outside the zone 515. In one or more embodiments, if at leastthree out of the at least four boundary crossing tests agree, the zoneboundary crossings 530 are used to determine if the position fix 520 islocated inside or outside the zone. In one or more embodiments, if threeout of the at least four boundary tests do not agree, the position fix520 is considered to be outside the zone 515.

Position fixes 520 that are on the special locations in the pixel map500 can yield specific location results. In one embodiment, positionfixes 520 that land on a zone boundary 510 are determined to be locatedoutside the zone boundary 510. In another embodiment, position fixes 520that land on a zone boundary 510 are determined to be located inside thezone boundary 510. In one embodiment, position fixes 520 that land on a“long and narrow protrusion”, which is only one pixel wide, can beconsidered to always be located inside the zone 515. In anotherembodiment, position fixes 520 that land on a “long and narrowprotrusion”, which is only one pixel wide, can be considered to alwaysbe located outside the zone 515.

FIG. 5B illustrates a pixel map 550 of a geographical zone in atwo-dimensional sense. The pixel map 550 is first presented to the useras a geographical map on a screen connected to a computing device. Inone embodiment, the user selects a rectangular shape 555 around thegeographical area 560 that the user desires to define. In anotherembodiment, the user may define a customized shape, which may be eithertwo or three dimensions. The rectangular shape is then divided intosmaller rectangles such that the area of the rectangle is divided into agrid. Each pixel in the grid can be activated to be part of thegeographical zone. In one embodiment, the user may activate each pixelby double-clicking on each pixel. In another embodiment, the user mayselect a smaller rectangular region, and mark the smaller rectangularregion as being part of the geographical zone 560 so that the pixelscontained within the smaller geographical zone are activated. In yetanother embodiment, the user may select a circular area as being part ofthe geographical zone 560, and all the pixels located in such circulararea would be activated. In another embodiment, the user may define anycustomized two- or three-dimensional geometrical or non-geometricalshape.

Once all the desired pixels are selected by the user as being part ofthe geographical zone 560, the rectangular shape 555 is mapped into apixilated computer image. In one embodiment, the pixilated computerimage contains the same number of pixels as the number of sections inthe grid. The pixilated computer image can then be loaded to thetransponder or subscriber device 105. The transponder or subscriberdevice 105 can be programmed to determine the position of the entitywith a simple calculation of whether the pixel in which the transponderor subscriber device's location falls is activated or deactivated. Inanother embodiment, the geographical zone is defined by selecting atwo-dimensional rectangular region, a three-dimensional rectangularregion, a circular region, cylindrical region, and/or a sphericalregion. The circular region, cylindrical region, and/or spherical regioncan each be defined by a waypoint.

An irregular zone or geographical zone may be defined by a collection ofwaypoints and pixilated images. Furthermore, each irregular zone mayhave additional parameters including, but not limited to, a speedthreshold of the entity parameter, a flag parameter such as a flagindicating a “no-fly zone”, a color coded parameter such as a specificcolor being used to indicate a danger or security threat, and acommunication enablement or disablement parameter.

When the transponder or subscriber device 105 enters or exits waypointsand zones, an event message is transmitted indicating what referencepoint or zone has been entered or exited. The event message can includea date relating to latitude, longitude, speed, direction, time, state ofthe inputs, odometer, event reason or source, and any other relevantinformation. Thus, the zone boundaries and waypoints allow the user totrack an individual, vehicle, or article through configurable boundariesor geographical zones, such as a state border or a specified route.

In one embodiment, the waypoint and zone events are configurable to oneor more assigned outputs. Meaning, when the transponder or subscriberdevice 105 enters or exits waypoints and zones, it can initiate anoutput. An output can consist of an LED light unit within the vehicle,article, and/or on the subscriber or transponder device associated withan individual.

Commands

The transponder or subscriber device 105 is also configurable to respondto various queries and to set commands sent wirelessly. A position querycommand can command the transponder or subscriber device 105 to returnthe last valid GPS position, position from the location nodes, speed,direction, time, input state, and other relevant state. The transponderor subscriber device 105 can also be configured to respond to a query.Upon receiving a query command, the transponder or subscriber device 105will return to the last valid GPS position, position from the locationnodes, speed, direction, time, input state, and other relevant state.

The transponder or subscriber device 105 is also configurable to respondto various query commands sent over the optional satellite modem 230.The satellite position query command commands the transponder orsubscriber device 105 to return the last valid GPS position, positionfrom the location nodes, speed, and time. The transponder or subscriberdevice 105 can also be configured to respond to a satellite odometerquery. Upon receiving this query command, the transponder or subscriberdevice 105 transmits the state of its inputs and running odometer value.Examples of other forms of query commands that are sent to thetransponder or subscriber device 105 include, but are not limited to, anInput and Output Signal Query, Analog to Digital Levels Query, PassengerCount Query, Firmware Version Query, Satellite Status Query, SatellitePosition and Velocity Query, and Satellite IO Query.

Another optional command is the alarm acknowledgement. This command issent to the transponder or subscriber device 105 to terminate thesending of a priority event (panic, medical or roadside assistance areexamples of priority events). When the alarm acknowledgement isreceived, no further priority messages for the current event aretransmitted.

In one embodiment, the command is to set a single output. This is usedto wirelessly change the state of an output to either active orinactive. An example would be to unlock the back door of an armoredtruck when it arrives at the bank. Another example is to turn on thefuel pumps for a tanker truck when it arrives at a gas station.

In another embodiment, the command may be to send a text message fromthe transponder or subscriber device 105 through the communicationnetwork to a device configured to receive and interpret text messages.

In another embodiment, the command is a configuration command toconfigure functionalities of the transponder or subscriber device 105 aspreviously discussed. Examples of configuration commands include, butare not limited to, Configure Timed Reporting, Set Odometer, Upload NewFirmware, Configure Excess Speed Event, Configure Excessive Idle Event,Configure Satellite Timed Reporting, Configure Power Level Critical,Configure Satellite Communication Port, Enable Event, Configure PriorityEvents, Enable Cellular Message, Enable Short-Range Radio Message,Assert Output Event, Configure GPS Filter, Enable Input, Set PassengerCount, Configure Smart Timed Reporting, Configure Scheduled Reporting,and Configure Satellite Scheduled Reporting.

The transponder or subscriber device 105 also may include a historyreporting component. Whenever the transponder or subscriber device 105cannot transmit data packets due to a lack of coverage via the principlecommunication media, the packers are stored in one of at least twohistory logs on an on-board flash memory storage device. When thetransponder or subscriber device determines that the communication linkhas been re-established, any packets stored in memory are sequentiallytransmitted, beginning with those messages identified as a priority. Forexample, emergency or roadside assistance would be a priority message,which would be the first message transmitted when the connection isre-established.

In an effort to combat GPS drift, two parameters are included to filterGPS positions received from the GPS receiver. The two parameters arerelated to maximum allowed speed and maximum allowed acceleration. Theparameters can be customized for a specific type of installation. If apacket is received from the GPS receiver and either of these twoparameters is exceeded, the position packet is discarded.

Backend Control System

FIGS. 6-1 through 6-4 illustrate a backend control system 150 utilizedfor vehicle fleet control. The backend control system 150 includes atleast a plurality of gateway systems 151-153, a codec 155, and anasynchronous routing system 159. In turn, as shown in FIG. 6-2, theasynchronous routing system 159 includes a web server 158, a pluralityof router systems 620, 622, a real time database 630, a history database642, and a fleet database 670.

The real time database 630 maintains records of the most recentinformation from the transponder or subscriber device such as location,speed, direction, and heading. The history database 642 maintainsrecords of all events and transactions that were received and sent fromthe asynchronous routing system 159. Finally, the fleet database 670keeps records of all the administrative entities such as the controlledmobile and static objects to which a transponder or subscriber device isassociated (e.g. a vehicle, user, fleet, and object).

The backend control system 150 can be configured to run on anycombination of computer servers. In one embodiment, the plurality ofcommunication gateway systems 151-153 runs on independent computersystems. In another embodiment, the communication gateways 151-153 runon a common computer system.

The communications gateway systems 151-153 direct data flow from each ofthe transponder or subscriber devices 105 into the backend controlsystem 150. The gateway systems 151-153 also direct commands and queriesto the appropriate transponder or subscriber device 105. Each gatewayestablishes and maintains a communication link with a communicationsnetwork 651-653. In one embodiment, the gateway is a Universal DatagramProtocol/Internet Protocol (UDP/IP) packet receiver and sender 151 whichconnects to an internet/cellular network 651. There may be more than oneUDP/IP gateway 151 transmitting and receiving data. The UDP/IP gateway151 allows the backend control system 150 to communicate withtransponder or subscriber devices 105 over GSM/GPRS, CDMA/1xRTT, andCDPD networks using UDP packets.

In another embodiment, the gateway system is a Short Message Peer toPeer (SMPP) gateway 152 that connects with a Short Message Service (SMS)network 652. A plurality of SMPP gateway systems 152 transmit andreceive data for the transponder or subscriber devices that communicateover SMS networks using an SMPP protocol. Each SMPP gateway system 152opens and maintains a continuous connection to the service provider'sShort Message Service Center (SMSC) for incoming data so that receptionof the transponder or subscriber device's 105 data from the SMSC can beguaranteed.

In another embodiment, the gateway system is a satellite gateway 153that connects to a satellite network 653. As illustrated in FIG. 1, thesatellite network 653 may include one or more satellites 130, and atleast one ground station 145. The satellite gateway 153 transmits andreceives data for the transponder or subscriber devices 105 thatcommunicate through satellite communication. In one embodiment, thesatellite communication protocol used may be that of Inmarsat satellitesusing eight-byte packets of data. The satellite gateway 153 opens andmaintains a continuous connection to the satellite network 653.

The communications between the asynchronous routing system 159 and thetransponder or subscriber devices are channeled through an appropriategateway system 151-154, as shown in FIG. 1. An appropriate gatewaysystem 151-154 is selected based on a unique combination of transponderor subscriber device manufacturer, the communications protocol, and theservice provider. For example, communications from a transponder orsubscriber device 105 that uses CDPD communication protocol would berouted through a different gateway system 151-154 than communicationsfrom a transponder or subscriber device 105 that uses SMS communicationsprotocol. Likewise, communications from transponder or subscriberdevices 105 that use the same communication protocol such as CDPD, buthave different service providers, would be routed through differentgateways.

As shown in FIG. 6-4, as the gateway system 151-153 receives eachinbound packet of data, the gateway system 151-153 labels each packet ofdata with the date and time of arrival, the transponder or subscriberdevice's 105 manufacturer information, and the transponder or subscriberdevice's 105 address information. The gateway system 151-153 thenrepackages the packet of data for transmission to the codec 155. Thegateway 151-153 then places the repackaged data into a queue 665 that isread by a codec 155.

When the gateway system 151-154 receives an outbound packet from anoutbound queue 661-664, the gateway system 151-154 uses the addressinformation to send the packet to the target transponder or subscriberdevice 105. If required, the gateway system 151-154 verifies beforetransmission that the gateway system 151-154 has an open and validconnection to the corresponding network 651-654. Each gateway system151-154 has at least one corresponding outbound queue 661-664. Forexample, each UDP/IP gateway 151 has at least one outbound UDP/IP queue661. Each SMPP gateway 152 has at least on outbound SMS queue 662. And,each satellite gateway 153 has at least one outbound satellite 663.Also, each SMTP mail gateway 154 has at least one outbound SMTP queue664.

After a packet of data is placed in the inbound queue 665, as shown inFIG. 6-1, the data coming from various networks is decoded into astandard data format. Likewise, before a packet is placed in an outboundqueue 661-664, as shown in FIG. 6-4, the data going to differentcommunications networks is coded from a standard data format into anetwork specific format. The coding and decoding of data is carried outby the codec (coder-decoder) 155. The codec 155 permits greaterflexibility because the introduction of new communication networkprotocols is transparent to the asynchronous routing system 159. Thus,if a new transponder or subscriber device model uses a newcommunications network protocol, the backend control system 150 does notneed to be upgraded. The system upgrades required would be a codec 155update and a new gateway, if necessary.

When a packet of data comes into the asynchronous routing system 159,each inbound packet that the codec 155 receives is first examined todetermine the transponder or subscriber device model. If the codec 155supports the specified transponder or subscriber device model, thepacket of data is translated from the transponder or subscriber device105 proprietary format into a standard system format. Once the codec 155has interpreted the data, the codec 155 then writes the data into aresponse queue 610, as shown in FIG. 6-2. If the codec 155 does notrecognize the transponder or subscriber device model, the codec 155 logsthe unsupported packet of data, and emails the packet of data to adesignated system or network technician.

When a packet of data is sent from the asynchronous routing system 159,the codec 155 determines the transponder or subscriber device model towhich the packet is sent. If the codec 155 supports the specifiedtransponder or subscriber device model, the data is translated from thestandard system format into the transponder or subscriber device 105proprietary format. Likewise, if the packet of data is sent to anotherdevice that is not a transponder or subscriber device 105, the codec 155determines if it supports that device, and if so, translates the packetof data to the appropriate format. Once the codec 155 has interpretedand encoded the data, the codec 155 places the packet of data into thequeue that corresponds to the appropriate type of network communicationprotocol. An SMS data packet would be placed into the outbound SMS queue662. If the codec 155 does not support the transponder or subscriberdevice model, the codec 155 will log the unsupported packet of data, andemail the packet of data to a designated system or network technician.

Once a packet of data is processed by the codec 155, it then getsprocessed. How the packet of data is processed depends upon whether itis an outbound or an inbound data packet. Outbound data packets areplaced in an appropriate outbound queue 661-664. Conversely, inbounddata packets are received by the asynchronous routing system 159 andplaced in a response queue 610, as shown in FIG. 6-2. The response queue610 feeds the data packets to the response router 620. The responserouter 620 determines if a client console 176, as shown in FIG. 1, istracking the transponder or subscriber device 105 associated with theincoming message. If so, the response router 620 routes the incomingmessage to the appropriate client console 176. Thus, the client console176 receives the message before any other process in the asynchronousrouting system 159. If no client console 176 is tracking the transponderor subscriber device 105 associated with the incoming message, theresponse router 620 places the incoming message into a new event queue621. The new event queue 621 feeds the incoming message to a new eventrouter 622. The new event router 622 analyzes each incoming message, anddetermines if the incoming message is associated with a new priorityevent for the transponder or subscriber device 105. The new event router622 determines if the incoming message is associated to a new event bysearching a real time database 630 for a similar event associated to thetransponder or subscriber device 105. If no event is recorded for thetransponder or subscriber device 105, or if the event is of highpriority, the new event router 622 sends a routing request to all clientconsoles 176 that have permission to view the incoming message. Therequest is intermittently sent to the client consoles 176 until at leastone client console 176 accepts the routing request. Once the routingrequest is accepted, the client console 176 adds the transponder orsubscriber device 105 to an inventory in that client console 176 so thatthe incoming message can be handled.

Asynchronously, a history queue 640 receives the inbound and outboundmessages for all transponder or subscriber devices 105. The inboundmessages are fed from the history queue 640 to the history recorder 641.The history recorder 641 geocodes all data packets that have a validlatitude and longitude. The geocoded information is saved in a historydatabase 641 to be used later for reporting and statistical analysis.

Incoming messages from transponder or subscriber devices 105 may also beforwarded to an email address, cellular telephone, or any othercommunications device. To achieve this functionality, the historyrecorder 641 also transmits the geocoded locations to remote notifyrouters 681 by placing the geocoded locations in a remote notify queue680. The remote notify router 681 that receives the geocoded locationand event information queries the fleet database 670 to determinewhether the configuration information associated with the transponder orsubscriber device 105 requires a notification to a communications device180, as shown in FIG. 1. If a notification is required, the remotenotify router 681 retrieves the contact information for the appropriatecommunications device 180. The remote notify router 681 then formats andencodes the message to be sent to the communications device 180. Themessage is placed in the outbound SMTP queue 664 to be sent through theSMTP gateway 154. Alternatively, the message can be placed in theoutbound SMS queue 662 to be sent through the SMPP gateway 152.

The real time database 630 is also updated with the new eventinformation associated with the incoming message. Thus, the real timedatabase 630 contains the latest information reported on a giventransponder or subscriber device 105. The real time database 630 isconnected to a web server 158. The web server 158 is directly connectedto the Internet 160 and allows users of a web-tracking application 171to make location requests, command requests 632, and report requests.When a web server 158 receives a location request from the web trackingapplication 171, the web server 158 queries the history database 642.The history database 642 contains all events in a chronological order.The web server 158 retrieves all transactions related to the webtracking application 171 query, and forwards the data to the webtracking application 171 for displaying to the user in a web browser.

When a web server 158 receives a location request from the web trackingapplication 171, the web server 158 queries the real time database 630for the corresponding transponder or subscriber device 105 information.The real time database 630 provides transponder or subscriber deviceinformation as related to the very last incoming message from theincumbent transponder or subscriber device 105. The web trackingapplication 171 may also send a command request 632 such as a query asto the position of the transponder or subscriber device 105. The commandrequest 632 is sent to the command receiver 690 which, in turn,processes the position request command by activating the appropriatetransponder or subscriber device 105 information. The message is encodedby the codec 155, placed in the appropriate outbound queue 661-664 andsent through the corresponding gateway system 151-154 to the transponderor subscriber device 105. The transponder or subscriber device 105 willthen send back a response. The backend control system 150 then processesthe response, and accordingly updates the real time database 630. Afterthe real time database 630 has been updated, the web server 158 mayrefresh the contents of the web tracking application 171, therebyshowing the new position of the transponder or subscriber device 105.

The command receiver 690 processes all commands pertaining to alloutbound messages to be sent to the transponder or subscriber devices105. The command receiver 690 may receive command messages from theclient consoles 176, the administrator consoles 175, and/or from the webservers 158. When the command receiver 690 receives a command message,the command receiver 690 labels each outbound message with the correcttransponder or subscriber device 105 address by searching a fleetdatabase 670, and retrieving the address information. Each message issent by the command receiver 690 to the codec 155 for encoding.

All of the commands that are processed by the command receiver 690 areultimately sent remotely to the transponder or subscriber device 105. Inone embodiment, the command is a Position Query. Upon receiving thisquery command, the transponder or subscriber device 105 returns its lastvalid position, speed, direction, time and input state. In anotherembodiment, the command is an Odometer Query. Upon receiving this querycommand, the mobile products return their last valid GPS position,position from the location nodes, speed, direction, time, input state,and running odometer value. In another embodiment, the command is anInput/Output Query. Upon receiving this query command, the transponderor subscriber device returns its last updated state of all inputs andall outputs (e.g., active or inactive). For any given input, the activestate is relative to the configuration of that specific input. Forinstance, if an input is configured to be active-low (H-L), then 0 voltsat the input translates into that input being “active.” If the input isconfigured to be active high (L-H), then 12/24 volts at the inputtranslates into that input being “active.”

In another embodiment, the command is a Time Report Set and/or HomeInternet protocol (IP). This command is sent to the transponder orsubscriber device to configure the reporting interval for the TimedReporting feature of the firmware. This command can also be used forsetting the transponder or subscriber device's destination IP address.This command allows the transponder or subscriber device to bereconfigured wirelessly in order to be able to transmit to a new controlcenter or home address if the IP address of the control center or homeaddress changed.

In another embodiment, the command is Set All Outputs. This command issent to the transponder or subscriber device to set all outputssimultaneously. Any individual output can be either high or low. Inanother embodiment, the command is Set Single Output. This command issent to the mobile products to set one individual output either high orlow. In another embodiment, the command is Enable/Disable Inputs andEvents. This command is sent to the transponder or subscriber device toenable/disable all known transponder or subscriber device features. Bothphysical and logical events can be individually enabled and/or disabled.While the physical and logical events can be disabled, the ability toquery the transponder or subscriber device for its location and statuscan remain enabled. In another embodiment, the command is an AlarmAcknowledgment. This command can be sent to the transponder orsubscriber device to terminate the sending of an emergency event, suchas panic, roadside assistance, or medical assistance. When the alarmacknowledgement is received, no further emergency messages for thecurrent event are transmitted from the transponder or subscriber device105.

The asynchronous routing system 159 interacts with various controlconsoles, as depicted in FIGS. 6-2 and 6-3. Reporting consoles 174connect to the fleet database 670 to display fleet information.Administrator consoles 175 also connect to the fleet database 670 toretrieve the transponder or subscriber device's information.Administrator consoles 175 also connect to the command receiver 690 tosend commands to the transponder or subscriber device 105. Operationsdata processors 173 connect to the fleet database 670 in order toretrieve configuration information for a specific user or transponder orsubscriber device 105. Finally, the client console 176 receivesinformation for a tracked transponder or subscriber device 105 from aresponse router 620, receives information for a non-tracked transponderor subscriber device from a new event router 622, and retrievesinformation from the fleet database 670. The client console alsotransmits commands to a transponder or subscriber device 105 by sendingthe commands to the command receiver 690.

An exemplary embodiment of the location system 2010 in FIG. 12illustrates the main components of the system 2010. The system 2010comprises a wireless communication device 2012 and a plurality oflocation transmitters or nodes. A plurality of location nodes 2014,2016, 2018 are depicted to illustrate that multiple location nodes canbe located within communication range of the wireless communicationdevice 2010 at any specific time.

Each location node 2014, 2016, 2018 contains a programmable transceivercommunication device incorporating a radio transceiver module 2020 and amicro-controller 2022. In alternative embodiments, each location node2014, 2016, 2018 may contain a separate transmitter and receiver insteadof a single radio transceiver module 2020. In exemplary embodiments, themicro-controller 2022 controls the radio transceiver module 2020,responds to queries sent wirelessly from the wireless communicationdevice 2012, and stores and retrieves detailed location information inthe form of data in the micro-controller's 2022 non-volatile memory.

Each location node's 2014, 2016, 2018 radio transceiver module 2020 willhave its own location node name, or friendly name. Selection parametersand the geographic position may be encoded and stored in the locationnode name. In exemplary embodiments, the location node name will includeinformation including, but not limited to, maximum power setting,installation identifier, floor number, payload type, node latitude andlongitude, and an integral checksum.

In another embodiment, the location node name is limited to 16characters and is encoded utilizing ASCII characters to efficiently andsimply name the location node.

Detailed location node location information is found in the memory ofeach micro-controller 2022 of each location node 2014, 2016, 2018. Inone example, the detailed location node location information isformatted into a database according to Table 1.

TABLE 1 Field Data Type Length BT_NAME CHAR 6 HOUSE_NO CHAR 10HOUSE_NO_SUFFIX CHAR 4 PREFIX_DIRECTIONAL ASCII 2 STREET_NAME CHAR 60STREET_SUFFIX ASCII 2 POST_DIRECTIONAL ASCII 2 POSTAL_COMMUNITY CHAR 32STATE ASCII 2 ZIP_CODE CHAR 10 BUILDING CHAR 40 FLOOR CHAR 5 UNIT_NOCHAR 5 UNIT_TYPE ASCII 2 LOCATION_DESCRIPTION CHAR 60

In exemplary embodiments, the detailed location information includes atleast the address including the street number, the street name, thelocal community, the state and the zip code. The detailed locationinformation may also include data including the name of the building,the floor number, the unit or room number, or type of room. In otherembodiment, the detailed local information may include any relevantother information to provide specific or complementary information forquicker identification of the location.

In exemplary embodiments, the wireless communication device 2012 of thepresent disclosure is a Bluetooth™ enabled device. In one or moreembodiments, the wireless communication device 2012 is a cell phone, alaptop computer, a pager, a PDA, or any other wireless communicationdevice with the ability to receive the detailed wireless communicationdevice location information from the location node 2014, 2016, 2018.

The wireless communication device 2012 includes software components tointeract with each of the radio transceiver modules 2020 in the locationnodes 2014, 2016, 2018. The wireless communication device 2012 willperiodically interrogate its environment, and when it is in range of alocation node 2014, 2016, 2018, the wireless communication device 2012will connect to, and query the location node 2014, 2016, 2018.

In the disclosed system and method, the wireless communication device2012 will receive selection parameter data from each location node 2014,2016, 2018. Utilizing these selection parameters, the location node willnarrow the plurality of location nodes 2014, 2016, 2018 to the mostpractically near location node 2014, 2016, 2018. This is necessarybecause the closest location node to a wireless communication device2012 on the second floor of a building could be on the ceiling of thefirst floor and, thus, be inaccessible from the second floor. In anexemplary embodiment, an algorithm 2050, as shown in FIGS. 13A and 13B,located within the wireless communication device 2012 is utilized todetermine the location node 2014, 2016, 2018 that is most practicallynear.

FIGS. 13A and 13B illustrate an exemplary embodiment of the algorithm2050 utilized by the wireless communication device 2012 to detect itslocation. The location node selection algorithm 2050 begins with ageneral wireless communication device discovery 2052 of all locationnode's 2014, 2016, 2018 located within communication range. The resultof this wireless communication device discovery 2052 is a list oflocation node names, also known as friendly names, and the associatedunique location node radio addresses. Because valid location node nameshave a special format and an integral checksum, radio wirelesscommunication devices 2012 that are not location nodes are easilyexcluded from this list. In one or more alternative embodiments, thewireless communication device 2012 performs a custom device discovery2052 by searching for wireless devices of at least one specificsubclass. Specific subclasses include, but are not limited to, locationnotes 2014, 2016, 2018 and specific types of wireless communicationdevices 2012, such as cell phones, pagers, PDAs, and/or laptopcomputers. Also, in some alternative embodiments, the wirelesscommunication device 2012 performs a custom device discovery 2052 bysearching for at least one specific wireless device 2012 operating in aspecific mode.

For example, if a building only has a single location node, and no othersurrounding buildings maintain a location node, this single locationnode could be set using a “force use” flag. This would allow for aquicker, more efficient selection and determination of the location ofthe location node. Another example would be where several location nodesare located in a small area within a building. These location nodescould also be set using a “force use” flag. This again would allow for aquick, efficient selection and determination of node location.

After the wireless communication device discovery process 2052completes, if only one valid location node has been discovered 2056,this location node is selected. If more than one valid location node hasbeen discovered then a series of steps begins to reduce this list downto one location node that is the most practically near to the wirelesscommunication device. If after any step, only one valid transmitterremains in the list the selection process ends with that location nodebeing selected.

As each location node is discovered by the wireless communicationdevice, the name is parsed to confirm if it is a valid location node. Atthis time, if a location node has a valid “force use” flag, thislocation node is selected as the location node that is most practicallynear. Use of the “force use” flag can reduce the selection process timedown to one or two seconds but should only be used when it is certainthat any wireless communication device within radio range must selectthat location node with its force use flag set as true.

In another embodiment, the algorithm 2050 may then utilize a step 2060to distinguish between different buildings or installations. Whenlocation nodes are installed, all the location nodes installed that arepart of the same installation are assigned the same identifier.

For example, if two commercial buildings are in close proximity, andboth have location nodes installed, the installation identifiers will bedifferent for each building. Therefore, if a wireless communicationdevice in one building is within radio range of a location node in theother building it can more easily select a location node within its ownbuilding and installation area.

In exemplary embodiments, the installation identifier is not intended toprovide a universally unique identification number but should provide aunique identifier for every installation within radio range of any otherinstallation having location nodes.

First, the wireless communication device determines how manyinstallation identifiers are in range of the wireless communicationdevice 2060. The wireless communication device will detect more locationnodes in the building where it is located. If there are unequal numbersof location nodes within the different installations 2074, then thelocation nodes in the building with fewer location nodes are removed2076 from the list of possible location nodes.

In another embodiment, the algorithm may utilize a step 2062 distinguishbetween different floors of a building or installation. When locationnodes are installed, all the location nodes installed that are ondifferent floors of the same installation are assigned different flooridentifiers in the location node name.

In this step 2062, the wireless communication device determines if morethan one floor number is represented within one installation identifier.If there are unequal numbers of location nodes on multiple floors 2064,the wireless communication device eliminates those locationstransmitters on the minority floors, i.e., on those floors which havethe smaller number of location nodes 2068 sensed. If at this point, onlyone location node is available, the wireless communication devicechooses this location node as the location node that is most practicallynear.

In another embodiment where equal numbers of location nodes exist onmore than two different floors within one installation identifier, thoselocation nodes on the upper most and lower most floors are removed fromthe list 2070. This step may be repeated until there are no more thantwo different floors within one installation identifier.

At this point, if more than one location node remains in the list afterthe above steps then a serial port profile connection is attemptedbetween the wireless communication device and each location noderemaining in the list 2072. If the connection is successful then thelocation node is queried for its received signal strength (RSS) for thatconnection 2074.

RSS is queried from the location node because the interface on thewireless communication devices does not generally support a query for anRSS value. If at least one connection and query for RSS is successfuland the RSS value associated with that location node is higher than theRSS value for all others 2076, then that location node is selected bythe wireless communication device as the location node that is mostpractically near to provide the detailed local information 2080.

In the next step, if more than one location node has an identicallyhighest RSS value retrieved then the “maximum transmit power” settingsare compared 2082. If one location node with highest RSS value has amaximum transmit power lower than the other(s) then this location nodeis selected 2084.

In another step, if all attempts at serial port profile connections andretrieval of RSS values have failed then the “maximum transmit power”settings encoded in the location node names of the remaining locationnodes are compared by the wireless communication device 2080. Inexemplary embodiments, the first character of the wireless communicationdevice name includes maximum power transit setting. If one maximumtransmit power setting is lower than all others then this location nodeis selected 2090 since, all other factors being equal, a location nodewith lower maximum transmit power will probably be most practically nearto the wireless communication device.

In the next step of the algorithm 2050, if, after all elimination stepsare complete and more than one location node remain in the list, thenone of the remaining location nodes is arbitrarily selected by thewireless communication device 2092.

After the algorithm 2050 has been run, when queried, the precisedetailed local information from the selected location node is returnedto the wireless communication device.

Another exemplary embodiment is shown in FIG. 14. Shown therein is asystem including a management system 2200 including a database 2300,a(n) Console(s) 2400, base stations 2100, LAN hub 2500 and locationnodes 2014, 2016, 2018. Consoles 2400 are utilized to administer thedatabase 2300 and configure the monitoring and messaging services.

Management base stations 2100 are modules equipped with power circuitry,a micro-controller, and preferably a radio transceiver such as aBluetooth™ radio and a Wi-Fi radio. The base stations 2100 areself-contained in packaging and can either be connected directly into aconstant power source or battery-powered.

The management system 2200 interacts with an enabled location nodeenvironment via management base stations 2100 preferably over awide-area network. The management system 2200, for example, maycommunicate with the base stations 2100 through their Wi-Fi radios,while the base stations 2100 communicate with the location nodes 2014,2016, 2018 though their Bluetooth™ radios. Only one base station 2100 isrequired per enabled environment, but multiple base stations 2100 can beused in sprawling areas or for load balancing.

In FIG. 15, area specific messaging provides the ability to delivermessages to enabled wireless communication devices within a specificarea, where the specific area could be defined by one location node2014, 2016, 2018 to an entire enabled environment. The management system2200 initiates messaging via the management base station(s) 2100, andpreferably utilizes a “daisy chain” approach to pass pending messages tolocation nodes 2014, 2016, 2018 that may be installed at locations farbeyond the range of any Bluetooth™ or Wi-Fi radio. Warnings aregenerated in the event a pending message cannot be delivered to alocation node 2014, 2016, 2018 defining part of or all of the specificarea.

Consoles 2400 are used to configure area-specific messaging, utilizing amap displaying the placement and range of every location node 2014,2016, 2018 within a messaging enabled environment. A message, itsseverity and its delivery path are then defined (or selected from a listof existing paths), beginning with a management base station 2100, andlinking a series of location nodes 2014, 2016, 2018. The message and itsdelivery path are then stored in the database 2300, along with itsdelivery schedule.

A message may be sent via a console 2400 to a base station 2100. Frombase station 2100, as shown in FIG. 16, the message is sent to the firstlocation node in a chain. Throughout the following discussion it is tobe understood that the nodes 2014, 2016 and 2018 may be continuouslyconnected or connected only on demand.

As illustrated in FIG. 17, this first node is location node 2014. Thelocation node 2014 will execute an algorithm 2700 described below andshown in FIG. 18.

Location node 2014 will begin execution of algorithm 2700 at operation2702 by coupling with a base station 2100 if a message is to be sent tobase station 2100 for forwarding to communication devices that arewithin range of the location nodes. Base station 2100 sends the messagesignal to the first location node 2014. Control is then passed tooperation 2704 where the incoming message signal is received by locationnode 2014. Control is then passed to operation 2706. Location node 2014replies to the base station 2100 with a receipt message acknowledgingthat the message was successfully received. Had location node 2014 beenin the middle of the chain instead of the current example where it isthe first location node of the chain, location node 2014 would have senta receipt message to the previous location node in the chain.

Control is then passed to query operation 2708. Query operation 2708asks whether the message is for that location node. If it is, then amessage flag is set so that the message is to be available in responseto a query by wireless communication devices within its vicinity. If themessage signal is not carrying the address for location node 2014, theanswer is no and control is passed to operation 2714. If the messagesignal is carrying the address of location node 2014, the answer is yesand operation is passed to operation 2710.

At operation 2710 a message flag is made available to wirelesscommunication devices in the vicinity when they perform their periodicinquiry or discovery of the location nodes. In one or more embodiments,the message flag contains information including, but not limited to, thetype of message and/or the severity of the message. When the messageflag is made available, the wireless communication device can thenretrieve the message from location node 2014.

Control is then passed to query operation 2712. Query operation 2712determines if the message signal is carrying the addresses of otherlocation nodes farther down the chain and if it is, control is passed tooperation 2714. If the message signal is not carrying any otheraddresses, control is passed to the return operation 2716.

At operation 2714 the message is forwarded to the next location node. Inthe current example that node is location node 2016.

Control is now passed to 2716 where the location node 2014 effectively“goes to sleep” and awaits further instructions from the base station2100 or to be queried again by a wireless communication device.

Area-specific messages may be initialized on a pre-defined schedule, orcan be initialized immediately via a console 2400. The initialization ofan area-specific message begins at a management base station 2100, andwill leap from one location node 2014, 2016, 2018 to the next as definedin the daisy chain sequence. Location nodes 2014, 2016, 2018 will storethe message in their flash memory if it is intended for them beforepassing that message on to the next location node 2014, 2016, 2018 inthe sequence. The message initialization results are returned to theinitiating management base station 2100 in the reverse sequence of thedaisy chain when the end of the daisy chain is reached. The managementbase station 2100 transmits the results to the management system 2200,which are then recorded in the database 2300.

An exception report is returned to the initiating management basestation 2100 in the event an exception is encountered during theinitialization of a message. The exception report is returned in thereverse sequence of the daisy chain beginning with the location node2014, 2016, 2018 generating the exception. The management base station2100 transmits the exception to the management system 2200, whichgenerates the appropriate notifications and records the exception in theDatabase 2300. The management system 2200 will attempt to continue theinitialization of the message utilizing alternate daisy chain path(s).

A message-pending flag is passed to enabled wireless communicationdevices as they interrogate, connect to and eventually select locationnodes 2014, 2016, 2018 during the execution of the selection algorithm.If the selected location node 2014, 2016, 2018 is determined to have amessage pending, and the severity level of that message falls within thecriteria set on that wireless communication device, the message may beautomatically downloaded and displayed on the wireless communicationdevice. For example, “canned” messages may be transmitted and displayedautomatically which could arise in emergency situations.

In another exemplary embodiment of operation of the system 2200, whichis shown in FIGS. 15 and 16, system monitoring may be used to verifythat every location node 2014, 2016, 2018 within an enabled environmentis running, has not been moved and its data has not been compromised.The management system 2200 initiates system monitoring via themanagement base station(s) 2100, and utilizes a “daisy chain” approachto communicate with the location nodes 2014, 2016, 2018 installed farbeyond the range of any Bluetooth™ or Wi-Fi radio. Warnings can begenerated and the daisy chain rerouted in the event an exception isencountered.

Consoles 2400 are used to configure system monitoring, utilizing a mapdisplaying the placement and range of every location node 2014, 2016,2018 within an enabled environment. A health check daisy chain is thendefined, beginning with a management base station 2100, and linking aseries of location nodes 2014, 2016, 2018. The specific series is thenstored in the management system 2200, along with its execution schedule.The management system 2200 will ensure that all location nodes 2014,2016, 2018 within an enabled environment are included in at least onehealth check series.

System monitoring will execute on a pre-defined schedule, or can belaunched manually via a Console 2400. The monitoring begins at amanagement base station 2100, and will then leap from one location node2014, 2016, 2018 to the next as defined in the daisy chain sequence.Each location node 2014, 2016, 2018 in the sequence verifies that thenext location node 2014, 2016, 2018 in the sequence is running, has notbeen moved and its data has not been compromised. The monitoring resultsare returned to the initiating management base station 2100 in thereverse sequence of the daisy chain when the end of the daisy chain isreached. The management base station 2100 transmits the results to thedatabase 2300.

Referring specifically to FIG. 17, an exception report is returned tothe initiating management base station 2100 in the event an exception,for example, at location node 2019, is encountered during systemmonitoring. The exception report is returned in the reverse sequence ofthe daisy chain beginning with the location node 2019 generating theexception. The management base station 2100 transmits the exception tothe management system 2200, which generates the appropriatenotifications and records the exception in the Database 2300. Themanagement system 2200 will continue system monitoring utilizing analternate daisy chain path 2021, indicated by solid lines in FIG. 17,until the compromised location node 2019 is fixed, replaced orpermanently removed from the system.

As a still further exemplary implementation of the disclosed system, amobile client can send its location through the network shown in FIGS.15 and 16. Here the system 2200 may be utilized to collect communicationdevice information, such as cell phone numbers, etc. In this case, anycommunication device may respond with a message such as “record that I'mhere”, or an equivalent signal, and thus the system may be used to trackpersonnel locations. The system 2200 may also be used to track mobilenodes attached to moving entities in a similar manner, since themessages being transmitted may simply be acknowledgment signals that themobile node is within response range of a location node 2014, 2016 or2018.

FIGS. 19A and 19B illustrate an exemplary mesh network 4001 of nodes4000 in communication with base stations 4004 and, in turn, incommunication with control centers 4008. A multi-dimensional, such asthree-dimensional, map is created using nodes 4000 in communication 4002with each other. Detailed location information from each location node4000 is downloaded to at least one mobile device 4010. A mobile device4010 is associated with at least one user, who is located at a specificarea within a geographical zone. Each mobile device 4010 is incommunication with at least one control center 4008 to download a two-or three-dimensional map of the location of the mobile device 4010and/or, in some embodiments, a two- or three-dimensional map of thelocation of a different mobile device 4010.

In exemplary embodiments, the mobile device 4010 of the presentdisclosure is a Bluetooth™ enabled device. In one or more embodiments,the mobile device 4010 is a cell phone, a laptop computer, a pager, aPDA, or any other wireless communication device with the ability toreceive the detailed mobile device location information from at leastone location node 4000. The type of wireless communication employed bythe system includes, but is not limited to, radio frequency (RF)communications and/or infrared communications.

The present application discloses a system for developing amulti-dimensional map of a multi-dimensional space for use by a user.The user being selectively an individual 4012, a vehicle, and/or otherentity. One or more geographical zones are utilized by the system. Thezones can be selectively preconfigured geographical zones. Each zoneincludes a plurality of spaced-apart nodes 4000, where the nodes 4000are arranged in a multi-dimensional sense about the zone. For example,in FIGS. 19A and 19B, the nodes 4000 housed in the building 4020 aredistributed in four separate mesh networks 4001. Each mesh network 4001is located in one of four specific zones. The four specific zonesdepicted are the first floor 4012, the second floor 4014, the thirdfloor 4016, and the fourth floor 4018 of the building 4020. In addition,each mesh network 4001 of nodes 4000 has associated with it at least onebase station 4004.

Data communications are sent between one or more of the nodes 4000(4002), one or more mobile devices 4010, and one or more control centers4008 (4006). Multi-dimensional mapping is affected according to theplacement of the nodes 4000, and the communications between the nodes4000, the mobile devices 4010, and the control centers 4008.

The mapping of the geographical space is affected in a three-dimensionalsense, selectively being defined by x, y and z axes or coordinates,which in some embodiments may correspond to latitude, longitude, andelevation. The nodes 4000 are enabled to communicate using GPS and/orBluetooth™ protocol. The nodes 4000 are located at various locationswithin the geographical space, which comprises of at least one zone. Thezones are typically defined as non-regular geometrical shapes. Such anon-regular shape is something different from a circle, square,rectangle, or a series of straight lines defining a bounded area. Assuch, the lines defining the non-regular geometrical shapes areirregularly shaped and/or curved to define the irregularity. In someembodiments, users have the ability to define and change the boundariesof the zones employed by the system.

In one or more embodiments, the nodes 4000 are enabled to communicateusing Bluetooth™ protocol to effect communications between nodes 4000and mobile devices 4010, which are each associated with at least oneuser. In some embodiments, the mobile devices 4010 are also enabled tocommunicate with each other using Bluetooth™ protocol. The nodes 4000are selectively part of a mesh network 4001, or other suitable networkconfiguration. The nodes 4000 selectively communicate with mobiledevices 4010 associated with users. The mobile devices 4010 beingselectively a cell phone, PDA, pager, or other computer device.

In different systems, the zone is affected in two or three dimensions,and this can be used to regulate the location of a user. The user can bea movable entity that is associated with a transponder or subscriberdevice 4010. The transponder or subscriber device 4010 being selectivelya cell phone, PDA, pager, computer, or device configured to be inwireless communication with other mobile devices 4010 and with nodes4000 in a wireless communication network.

Mapping is attained by loading a plurality of mapping coordinates from acomputer device to a memory module of a transponder or subscriber device4010, or by the user directly loading a plurality of mapping coordinatesto a memory module of the transponder or subscriber device 4010. Themapping coordinates are used to generate a pixilated image. Thepixilated image is configured to form a contiguous array of pixels thatenclose a shape in the pixilated image, whereby the enclosed shape formsa geographical space.

A user can enter geographical coordinates on a computer device, or on atransponder or subscriber device 4010, by entering numerical values forthe coordinates of a specific location or locations. For example, theuser can enter numerical values for the longitude, latitude, andelevation of a specific location. Conversely, a user can entergeographical coordinates on a computer device, or on a transponder orsubscriber device 4010, by selecting points on a map displayed on adisplay screen by using a cursor to click on those point locations onthe map. The computer device, or transponder or subscriber device 4010,will calculate the corresponding geographical coordinates for each pointon the map that has been selected by the user.

The system for mapping a geographical space comprises communicatingmapping data between communication nodes 4000 and at least one selectedmobile communication device 4010. An array of communication nodes 4000is arranged about a two- or three-dimensional geographical space. One ormore different mobile communication devices 4010 are in communicationwith different communication nodes 4000 when the devices 4010 are withinrange of one or more selected nodes 4000. A mobile device 4010 isassociated with the respective nodes 4000 such that the mobile device4010 is locatable within the three-dimensional space.

In one or more embodiments, the mobile devices 4010 communicate with thenodes 4000 wirelessly via RF using Bluetooth™ protocol. When a mobiledevice 4010 determines its most practically near node 4000, the mobiledevice 4010 will download from that node 4000 the location informationof that node 4000. The mobile device 4010 can use this locationinformation in order to generate and display a two- or three-dimensionalmap of the mobile device's 4010 position within a geographical areaand/or zone. In addition, the node 4000 will transmit wirelessly via RFusing Bluetooth™ protocol the location information of the mobile device4010 to the node's 4000 associated base station 4004, or to other nearbynodes 4000 within the node's 4000 mesh network 4001. The base station4004 will, in turn, either communicate the location information of themobile device 4010 via Wi-Fi to other base stations 4004, or communicatethe location information of the mobile device 4010 via Internet, Wi-Fibridging, and/or Ethernet to at least one control center 4008.Conversely, the location information of the mobile device 4010 may becommunicated from nearby node 4000 to nearby node 4000 within the meshnetwork 4001 in a daisy-chain arrangement until the location informationof the mobile device 4010 is finally communicated to at least one basestation 4004 associated with the nodes' 4000 mesh network 4001.

In one or more embodiments, the nodes 4000 communicate with each otherwirelessly via RF using Bluetooth™ protocol (4002). In some embodiments,the nodes 4000 also communicate with the mobile devices 4010 wirelesslyvia RF using Bluetooth™ protocol (4003). In one or more embodiments, themobile devices 4010 have the ability to communicate with each otherwirelessly via RF using Bluetooth™ protocol. In some embodiments thenodes 4000 communicate with base stations 4004 wirelessly via RF usingBluetooth™ protocol (4005). In some embodiments, the base stations 4004communicate with each other via Wi-Fi (4006). In one or moreembodiments, the base stations 4004 can communicate with the controlcenters 4008 by various means including, but not limited to, Internetcommunications, Wi-Fi bridging, and/or Ethernet communications (4007).

In one or more embodiments, a first mobile device 4010 may submit alocation query to a second mobile device 4010 for that second mobiledevice's 4010 location information. In this embodiment, the first mobiledevice 4010 will transmit a specific location query to at least one node4000 that is located within communication range of the first mobiledevice 4010. The at least one node 4000 will then transmit the locationquery to the node's 4000 associated base station 4004, or to othernearby nodes 4000 within the node's 4000 mesh network 4001. The basestation 4004 will, in turn, either communicate the location query viaWi-Fi to other base stations 4004, or communicate the location query viaInternet, Wi-Fi bridging, and/or Ethernet to at least one control center4008. Conversely, the location query may be communicated from nearbynode 4000 to nearby node 4000 within the mesh network 4001 in adaisy-chain arrangement until the location query is finally communicatedto at least one base station 4004 associated with the nodes' 4000 meshnetwork 4001.

Once the location query reaches the control center 4008, the controlcenter 4008 will route the location query to at least one base station4004 that is associated with the mesh network 4001 of nodes 4000 thatare in close proximity to the second mobile device 4010. Once thelocation query is downloaded onto the second mobile device 4010, thesecond mobile device 4010 will display the location query to itsassociated user. If the user wishes to send his/her location informationto the user associated with the first mobile device 4010, the user willinput a positive response in the second mobile device 4010.

When the second mobile device 4010 receives a positive response to thelocation query, the second mobile device 4010 will transmit thatresponse to at least one node 4000 that is located within communicationrange of the second mobile device 4010. The at least one node 4000 willthen transmit the response to the node's 4000 associated base station4004, or to other nearby nodes 4000 within the node's 4000 mesh network4001. The base station 4004 will, in turn, either communicate theresponse via Wi-Fi to other base stations 4004, or communicate theresponse via Internet, Wi-Fi bridging, and/or Ethernet to at least onecontrol center 4008. Conversely, the response may be communicated fromnearby node 4000 to nearby node 4000 within the mesh network 4001 in adaisy-chain arrangement until the response is finally communicated to atleast one base station 4004 associated with the nodes' 4000 mesh network4001.

Once the positive response reaches the control center 4008, the controlcenter 4008 will then retrieve the geographical location information forthe second mobile device's 4010 most recent location. This locationinformation is then sent by the control center 4008 to at least one basestation 4004 that is associated with the mesh network 4001 of nodes 4000that are in close proximity with the first mobile device 4010. The atleast one base station 4004 will route the location information throughat least one node 4000 back to the first mobile device 4010. Once thefirst mobile device 4010 receives this location information, the firstmobile device 4010 will use this location information in order togenerate and display a two- or three-dimensional map of the secondmobile device's 4010 position within a geographical area and/or zone. Inone or more embodiments, the first mobile device 4010 will display thesecond mobile device's 4010 position in relation to the first mobiledevice's 4010 position on the multi-dimensional map. In someembodiments, the first mobile device 4010 will display navigationaldirections from the first mobile device's 4010 location to the secondmobile device's 4010 location. In one or more embodiments, the firstmobile device 4010 can transmit location queries either directly to thesecond mobile device 4010, through at least one node 4000 to the secondmobile device 4010, or through at least one node 4000 and at least onebase station 4004 to the second mobile device 4010.

In one or more embodiments, a first mobile device 4010 may initiallyconfigure a selective permission to allow specific subscribersassociated with mobile devices 4010 to receive the first mobile device's4010 location information. In these embodiments, the first mobile device4010 will transmit permission instructions to at least one node 4000that is located within communication range of the first mobile device4010. The at least one node 4000 will then transmit the permissioninstructions to the node's 4000 associated base station 4004, or toother nearby nodes 4000 within the node's 4000 mesh network 4001. Thebase station 4004 will, in turn, either communicate the permissioninstructions via Wi-Fi to other base stations 4004, or communicate thepermission instructions via Internet, Wi-Fi bridging, and/or Ethernet toat least one control center 4008. Alternatively, the permissioninstructions may be communicated from nearby node 4000 to nearby node4000 within the mesh network 4001 in a daisy-chain arrangement until thepermission instructions are finally communicated to at least one basestation 4004 associated with the nodes' 4000 mesh network 4001.

Once the permission instructions reach the control center 4008, thecontrol center 4008 will process the permission instructions. Once thecontrol center 4008 has processed the permission instructions, thecontrol center 4008 is configured to send the location information ofthe first mobile device 4010 to specific selected subscribers associatedwith mobile devices 4010 according to the permission instructions. Inone or more embodiments, the control center 4008, the base stations4004, and/or the location nodes 4000 may process the instructions and/orbe configured to send the location information of the first mobiledevice 4010 to specific selected subscribers associated with mobiledevices 4010 according to the permission instructions.

In these embodiments, a second mobile device 4010 will submit a locationquery for the first mobile device's 4010 location information. In theseembodiments, the second mobile device 4010 will transmit a specificlocation query to at least one node 4000 that is located withincommunication range of the second mobile device 4010. The at least onenode 4000 will then transmit the location query to the node's 4000associated base station 4004, or to other nearby nodes 4000 within thenode's 4000 mesh network 4001. The base station 4004 will, in turn,either communicate the location query via Wi-Fi to other base stations4004, or communicate the location query via Internet, Wi-Fi bridging,and/or Ethernet to at least one control center 4008. Conversely, thelocation query may be communicated from nearby node 4000 to nearby node4000 within the mesh network 4001 in a daisy-chain arrangement until thelocation query is finally communicated to at least one base station 4004associated with the nodes' 4000 mesh network 4001.

Once the location query reaches the control center 4008, the controlcenter 4008 will process the location query and determine if the secondmobile device 4010 is associated with one of the specific selectedsubscribers that were listed in the first mobile device's 4010permission instructions. If the control center 4008 determines that thesecond mobile device 4010 is associated with one of the specificselected subscribers that were listed in the first mobile device's 4010permission instructions, the control center 4008 will route a messagecontaining the current location information of the first mobile device4010 to at least one base station 4004 that is associated with the meshnetwork 4001 of nodes 4000 that are in close proximity to the secondmobile device 4010.

Once the message containing the currently location information of thefirst mobile device 4010 is downloaded onto the second mobile device4010, the second mobile device 4010 will display the locationinformation of the first mobile device 4010. This location informationincludes, but is not limited to, a two- or three-dimensional map showingthe location of the first mobile device 4010 in relation to the locationof the second mobile device 4010; a two- or three-dimensional mapshowing the location of the first mobile device 4010; and/or detaileddirectional instructions of how the second mobile device 4010 will needto travel to reach the current location of the first mobile device 4010.

Conversely, if the control center 4008 determines that the second mobiledevice 4010 is not associated with one of the specific selectedsubscribers that were listed in the first mobile device's 4010permission instructions, the control center 4008 will route a denialmessage to at least one base station 4004 that is associated with themesh network 4001 of nodes 4000 that are in close proximity to thesecond mobile device 4010. In at least one embodiment, the denialmessage will notify the subscriber associated with the second mobiledevice 4010 that he or she is not granted access to the current locationinformation of the first mobile device 4010. Once the denial message isdownloaded onto the second mobile device 4010, the second mobile device4010 will display the denial message.

With this system, it is possible to obtain mapping not only in alatitude/longitude sense, but also in an elevational sense. The nodes4000, for instance, are placed on different floor levels 4012, 4014,4016, 4018 of a high-rise building 4020 to allow for mapping in anelevation sense. In addition, this system provides for fine-resolutionmapping of a geographical location. Current GPS systems can determine alocation of a building 4020 in a relatively course manner, namely astreet address. The disclosed system includes nodes 4000 that provideenhanced fine-resolution mapping within a building 4020, and not only ona two-dimensional basis, but rather on a three-dimensional basis of thedifferent floors 4012, 4014, 4016, 4018 within the building 4020.

FIG. 20 illustrates an exemplary system for data mining andcommunications with users associated with mobile devices that arelocated within particular geographical areas.

In this system, mobile devices 4010 that are related to at least oneuser that is located in a specific area, or zone, at a geographicallocation are in communication 4003 with nodes 4000 that are locatedwithin that specific area, or zone. The at least one user can be anindividual 4012, vehicle, or article. The nodes 4000 are incommunication with at least one control center. The nodes 4000 downloaduser profile information and/or location information from the mobiledevices 4010, and transfer that profile information and/or locationinformation to at least one control center. The user profile informationincludes, but is not limited to, a history of geographical locationsthat the user has visited, the amount of time the user spent in each ofthose locations, patterns of location activity of the user, and patternsof shopping habits of the user.

The nodes 4000 can transmit the profile information and/or locationinformation to the control center either directly to the control center,through at least one node 4000 to the control center, or through atleast one node 4000 and at least one base station that is associatedwith the at least one node 4000 to the control center. Once the profileinformation and/or location information reaches the control center, thecontrol center processes the information. Once the information isprocessed by the control center, the control center employs a messagingsystem to send messages to specific mobile devices 4010, according tothe personal profiles of the mobile device users and/or the location ofthe mobile device users relative to specific nodes 4000. In one or morealternative embodiments, the nodes 4000, the base stations, and/or thecontrol centers process the information and/or use a messaging system tosend messages to specific mobile devices 4010, according to the personalprofiles of the mobile device users and/or the location of the mobiledevice users relative to specific nodes 4000.

Data mining and commercial communications are possible with users thatare associated with mobile devices 4010 and located in particulargeographical areas. For instance, when a user associated with a mobiledevice 4010 is located in a specific area of a shopping mall or a hotel,advertisements, promotions or suggestions that relate to that specificarea of the shopping mall or hotel are downloaded real time to theuser's mobile device 4010 for the user. For example, when the user'smobile device 4010 is located within communication range of a node 4000that is in close proximity to a restaurant or buffet 5004, the user maybe offered wining and dining advertisements, promotions, and/or couponsfor that particular restaurant or buffet 5004. In another example, whenthe user's mobile device 4010 is located within communication range of anode 4000 that is in close proximity to a show ticketing counter 5002,the user may be offered show advertisements, promotions, and/or couponsfor various show tickets sold at the ticketing counter 5002.

In a store environment, special advertisements can be offered to a user,depending on the user's perceived shopping habits or motion throughoutthe store. For instance, a person who spent a lot of time in the cameradepartment of the store can strategically be messaged about promotionsfrom that specific department. The behavior of the user can be part ofthe profile. Behavior of a user can include, but is not limited to, theamount of time the user spent in the vicinity of different nodes withinthe environment, the purchasing patterns of the user, the product orservice preferences of the user, the commercial enquiries of the user,the dining preferences of the user, and the entertainment preferences ofthe user. In one or more embodiments, a control system is used togenerate a profile of a user. For example, if the user purchased variousdifferent products, this product purchasing data can be fed into acontrol system to create and/or update the user's profile.

In a hotel environment, for instance, a casino 5000, a past profile of auser can be preloaded onto a mobile device 4010 associated with thatuser when the user checks into the hotel. The past profile may have beengenerated from the user's behavior during the user's prior stays at thehotel. This past profile can be updated according to the user's movementthroughout the hotel and actions during the user's stay at the hotel.

In this system, message communications can being targeted to at leastone or multiple users. This system permits a control center to be ableto control and/or monitor individuals 4012, vehicles and other mobileentities. The system utilizes at least one geographical zone. The zonecan be a selectively preconfigured geographical zone, and will include aplurality of nodes 4000.

Messages are sent between one or more of the mobile devices 4010associated with at least one user, one or more nodes 4000, one or morebase stations, and/or one or more control centers. The messagecommunications are targeted to at least one user. The nodes 4000 arearranged in a multi-dimensional sense, the multi direction senseselectively being a three-dimensional sense in the x, y and z axes orcoordinates. Data is obtained and mined according to the location of theuser's mobile device 4010 in relation to the placement of the nodes 4000in a multi-dimensional sense.

In one or more embodiments, the mobile devices 4010 are Bluetooth™equipped. The mobile devices 4010 communicate via RF using Bluetooth™protocol to Bluetooth™ enabled location nodes 4000 in a mesh network.When a mobile device 4010 is located within the range of certainlocation nodes 4000, specific events are triggered. These specificevents include, but are not limited to, the downloading of a commercialmessage, such as an advertisement, to the user's mobile device 4010 forthe user.

The selected nodes 4000 can communicate the location information of themobile device 4010 associated with a user. The selected nodes willtransmit the location information to a central station either directlyor via other nodes 4000 within at least one mesh network. The meshnetwork may include the use of relay stations and/or intermediatesupplementary stations.

A user is associated with a mobile device 4010, or transponder orsubscriber device 4010. The device 4010 being selectively a cell phone,PDA, pager, computer, or device which is configured to be in wirelesscommunication with other devices through a suitable network.

FIG. 21 illustrates an exemplary system of a multi-dimensional meshnetwork of nodes for communicating emergency messages to users.

At least one geographical zone 6006, 6008, which can bemulti-dimensional, such as in three dimensions, can be utilized toregulate the location of movable entities and their actions within thegeographical zone 6006, 6008. Detailed location information isdownloaded from nodes 4000 to a mobile device 4010 within a geographicalzone 6006, 6008. A mobile device 4010 associated with at least one userlocated in a specific area of a geographical zone 6006, 6008communicates with a control center through at least one node 4000.Mobile devices 4010 interact with location nodes 4000 that are incommunication range. A messaging system is used to send emergency andsecurity communications to users associated with mobile devices 4010that are located in particular locations.

The present system controls, regulates, and monitors users in anemergency or security environment. Users can include individuals,vehicles, and other moving entities. Regulating a user comprises atleast one of monitoring, controlling, and visualizing the movement in aspecific geographic zone 6006, 6008 of a mobile device 4010 associatedwith a user. The geographic zone 6006, 6008 can be a multi-dimensionalzone selectively in a three dimensional sense having x, y and z axes orcoordinates. The geographical zone 6006, 6008 is a zone that includes amesh network of nodes 4000.

Messages are sent between one or more of the mobile devices 4010, andone or more control stations. Message communications relating tosecurity and/or an emergency are targeted to at least one or multipleusers. The messages are focused, target specific, and dependent on thelocation of the nodes 4000 arranged in a multi-dimensional sense in thegeographic zone 6006, 6008. This system creates a security supportsystem utilizing user location data in relation to node 4000 placement.

The mobile personal devices 4010 associated with users are Bluetooth™equipped, and communicate wirelessly via RF using Bluetooth™ protocol tolocation nodes 4000. When an emergency and/or security event occurs, acentral station and/or intermediate supplementary station transmitsemergency and/or security notifications to mobile devices 4010associated with users located within at least one specific geographiczone 6006, 6008 of nodes 4000 in a mesh network. The emergency and/orsecurity notifications are transmitted to the users' personal devices4010 selectively via at least one node 4000 within a mesh network, orvia at least one node 4000 and through at least one relay station.

In some embodiments, when an emergency and/or security event occurs, atleast one user associated with a mobile device 4010 enters an emergencyand/or security notification into their corresponding mobile device4010. The notification may be entered into the mobile device 4010textually, verbally, and/or by dialing an “emergency and/or securitydesignated phone number or code,” for example the dialing of “911.” Theemergency and/or security notification is then transmitted to a centralstation and/or intermediate supplementary station for processing. Oncethe notification is processed, the central station and/or intermediatesupplementary station transmits emergency and/or security notificationsto mobile devices 4010 associated with users located within at least onespecific geographic zone 6006, 6008 of nodes 4000 in a mesh network. Theemergency and/or security notifications are transmitted to the users'personal devices 4010 selectively via at least one node 4000 within amesh network, or via at least one node 4000 and through at least onerelay station.

In this system, a plurality of coordinates relating to the emergencylocation 6009 are entered into at least one control center computer. Thecontrol center computer processes these location coordinates anddetermines which geographical zones 6006, 6008 are in close proximity tothe emergency location 6009. The control center then transmitscustomized emergency messages to the mobile devices 4010 that arelocated within those geographical zones 6006, 6008.

For example, as shown in FIG. 21, the emergency depicted is a small fire6009 located on the fourth floor of the chemistry building 6000. Thecoordinates of the fire 6009 are entered into the control center'scomputer. The control center computer processes these coordinates, anddetermines that the closest geographical zones to the fire 6009 arezones 6008, and the next closest geographical zones to the fire 6009 arezones 6006. Next, the control center transmits specific emergencymessages to the mobile devices 4010 associated with the users located inzones 6008 and 6006. Since the users in zones 6008 are closer to thefire 6009 than the users in zones 6006, the users located in zones 6008will receive emergency messages indicating that they are in very closeproximity to the fire 6009 and the users located in zones 6006 willreceive emergency messages indicating that they are in relatively closeproximity to the fire 6009. Thus, the emergency messages can be tailoredfor each specific geographical zone 6008, 6006.

The messages are sent between one or more of the nodes 4000 and one ormore mobile devices 4010 in a selected geographical zone. The nodes 4000and the mobile devices 4010 are enabled selectively to communicate withGPS and with Bluetooth™ protocols. The nodes 4000 selectivelycommunicate with users associated with a mobile device 4010, the device4010 being selectively a cell phone, PDA, pager, or computer device.

In an emergency or security environment, data is communicated betweencommunication nodes 4000 and a selected mobile device 4010 using thegeographical zone as a selected area for communication. Messages aresent between one or more of the mobile devices 4010, and one or morecontrol stations, where the message communications are targeted to atleast one or multiple users. The nodes 4000 are arranged in amulti-dimensional sense. The security support system utilizes userlocation data of movable entities, and the existence of emergency andsecurity conditions.

The system permits for individual, vehicles or other persons to becommunicated to in areas and spaces that can be isolated and separatedfrom other areas and spaces. In this manner if there is a securitysituation in one place, individuals or vehicles or other mobile entitiescan be targeted with messages or instructions to remain in a locationremoved or isolated from a danger area.
